CONCRETE BUILDING FORM.

Application filed November 17, 1924. Serial No. 750,410.

To all whom tif/nay concern.

Be it known that I, HENRY C. RIEsBoL, a citizen of the United States, residing at New York city7 in the county of'New York and State of New York, have invented new and useful Improvements in Concrete Building Forms,of which the following` is a specification.

,This invention relates to improvements in concrete building forms for the construction of concrete walls formed with vertical ribs on the inside face thereof, whereby the rib is formed simultaneously with the forming of a wall.

Another object of the invention resides in the provision of a plurality of channel members adapted to be held in vertical position by a form and which form co-acts with the channel members for forming the ribs on the wall and to which the laths are attached for supporting the plaster in spaced relation with the wall, whereby air space is provided between the wall and the plaster to prevent the condensation of a wall from contacting with the plaster which often results in the cracking and spoiling of the same. f

Another object of the invention is to provide an improved means in the assembling `and disassembling of concrete wall forms which is simple in construction, cheap of manufacture and which will reduce the cost of labor in the use of the form to a miniuuiun.

A still further object of the invention resides in the provision of a form and a supporting structure therefor which is adapted for use in the pouring of walls of one story in height whereby Vthe cost of the scaffolding now employed for this purpose is greatly reduced.

With these and other objects in view, vthe invention resides in certain novel constructionv andcombination `and arrangement of parts, the essential features of which are hereinafter fully described, `are particularly pointed out in the appended claims, and arefillustrated in the accompanying drawing, in which Figure 1 is a horizontal sectional View showing a plurality` ofrib forming members in position for the forming of a conn crete wall.

Referring more particularly to the drawing, the reference numeral 10 designates a metallic ychannel member which is U-sha'ped in horizontal section and which is formed flanges Any number of channel members may be employed in the construction of a wall', theV outer'section 13 includes a horizontal liner ltany number of which may be provided and arranged in spaced relation and which enga-ge vertical beams 17 carried by the wall forming sections 18; The sections 18 are arranged in intimate contact with each other to form the outer wall of a mold cavity 19 formed at the space betweenthe outer and inner sections 13 `and 14;. The inner section 14 includes a plurality of inner wall forming sections 2O between the meeting edges of which one of the channel members 10 is arranged. The ends of the sections 20 abut the fianges 11 which prevent movement of the sections toward thefouter section 13. The'sections 2() are held in position by a horizontal liner 21 which is supported by brackets 22 carried by the channel members 10. Any number of these liners may be employed, but for the ordinary height of wall, three have been foundto be sufficient. The liners 16 and 21 are held tight against the inner and outer wall forms by wires 22 which are looped about the liners and twisted as at 23 for a distance approximating the thickness of the wall to be formed.

Additional means is provided for holding the outer sections 18v in vertical position which` includes bolts 24 which extend through openings 25m the body portionof the channel members and which extend into the cavity 19. The bolts are inserted at suitable points along the length yof thechannel member and each receives a nut 26 upon its threaded end. Each nut is formedwith an eye 27 to which the-free lends of a wire 28 are connected, the wires extending through the outer wall sections-and around the meeting beams 17.

The channel members removably support wood inserts 29 which are arranged on the inside thereof and are adapted to be embedded in the ribs of thewall during the formation of the same and which inserts are formed with anchoring elements 30 which securely hold the inserts embedded.

After the parts just described have been assembled the reinforcing rods 81 are placed in the mold cavity to extend both horizontally and vertically and are arranged in suitable spaced relation. The wall form is now ready to receive the concrete, after which the form is left in position until the concrete has ample time to set. Then removing the form after the formation of the wall, the wires 9.2 and QS are clipped adjacent the' surface of the` wall to permit the liners 16 and 21 to be removed, after which the bolts '24; are unscrewed from the nuts 2G, thereby lea-ving` the nuts, bolts and the wires 2S in the wall structure. The securing elements which connect the wood inserts with the channel members arefnow removed as are the sections 20. This now leaves the channel members free whereby the wall is clear of any form structure, it being understood that the outer wall forming sections 18 have been previously removed with the liners 1G after the severing of the wires 22 and 28.

Figure 2 of the drawing clearly shows the wall structure in its completed condition -wherein it will be noted that the brace rods 15, the twistedportions hlportions of the wire 2Sv and the nuts 26 are leftin the wall to o o-operate with the reinforcing rodsjfll `for adding strength to the same and the saving of time in the removal of the form. It will be seen that the 'channel members serveto form spacedribs-BQ yon the'inner surfaceof the wall designated by thenumei-al Awherein the wood inserts are embedded. and to which "fur'ring strips are secured and to which strip laths are fastened 'for 'receiving the inner plaster. The ribs 32 serve to space the lplaster from the wall proper whereby air isjfree to circulate,fit also being found useful for thel passage'of electric wires when wiring thc'building for electricity.

lVhile I have described what^`1deem to be the mostdesirable `embodiment of my inventiom-it is obviousthatmany ofthe fdetails maybe varied'without in any way departing from the rspirit of my invention,

and 1 therefore do not limit myself to the exact details of construction herein set forth nor to anything less tha-n'the whole of my invention limited only `by the appended claims.

That is clainiied as new is 1. A building form including a plurality of spaced-channel members, inner wall forming sections between said channel members, and means on said channel members for removably supporting` a horizontal beam for holding said channel members in alignment.

2. A building form including a plurality of spaced channel members, inner wallforming sectionsbetween said channel members, and means on said channel members `for removably supporting a horizontal beam'for holding said channel members in alignment, outer wall forming sections spaced from said inner wall fo'rn'iing sections'to define a mold cavity,-and wires connecting said beam with a portion of said outer wall forming sections.
